MULTIPLE-Fuss CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 569,692, dated October20, 1896.

Y Application iled February 26, 1894. Serial No. 501,623, (No model.)

Be it known that I, GARDNER T. VooRHEns, of Boston, in the county ofSuffolk and Stat-e of Massachusetts, have invented a new and usefulMultiple-Fuse Cut-Out, of which the following is a specification,reference being had to the accompanying drawings,in which-- Figure 1 isa central section through my new cut-out at line 1 1 of Fig. 3. Fig. 2is a similar sectional View on a line 2 2 of Fig. 3. Fig. 3 is a planview of my new device, partly in section, on a line at 3 3 of Fig. 1,looking down in Fig. 1. Fig. 4 is a cross-sectional view on the line at3 3 of Fig. 1, looking up in that figure, the fuse-carrier beingremoved. Fig. 5 is an end view of the fuse-carrier, showing thepartitions which separate the fuses, the fuses and exposed contact beingremoved for greater clearness. Figs. G, 7, and 8 show modifications ofthe plug. Fig. 9 shows a modification of the fuse-contacts and fuses.

Generally stated, the object of my invention is to produce a cheap andefficient multiple-fuse cut-out; and the nature of my invention is thecombination of, iirst, a base having a socket to receive afuse-carrier;second, a fuse-carrier having a plurality of fuses, and, third,conductors and contacts necessary to complete an operative multiple-fusecutout.

In the drawings illustrating the best form of my invention now known tome, 1 is the base; 2, the socket which receives the fusecarrier 4c, aseries of fuses; 5, a series of fuse-contacts at one end of the fuses;6, an exterior conductor adapted to contact with socket 2 when thefuse-carrier 3 and socket are together. This exterior conductor ispreferably a shell of conducting material and is called herein aconducting-shell, because that is the preferred construction, althoughit is not essential to my invention that this exterior conductor G(preferably in the form of a shell) should surround the side walls ofthe fuse-carrier, and its area may be diminished, if desired, as will beplain to all skilled in the art.

7 and S are openings in the conductingshell; i), a conductor whichconnects conductor G with the fuses 4; seratz'm, (preferably makingcontact directly with the fuse-contacts 5,) and 10 is a fuse-contact atthe other ends of the fuses.

Base l supports the fuse-carrier-receiving socket 2, which is ofconducting material and in electrical connection with a lead L. Lead Lconnects electrically with the fuse-contact 10, which, to insure thebest electrical connection, is common to ends of all the fuses, althoughit might be subdivided into a series of fuse-contacts like the contacts5, if so desired. Preferably, a metal bar or electrode 11 connects abinding-screw 12 (to which lead L is secured) with the socket 2, and abar 13 preferably connects fuse-contact 10 with a binding-screw 14, towhichvlead L is secured, this lead L being insulated from socket 2conveniently by the insulation 15. In this instance socket 2 and shell 6are screwed together, as shown, and the current goes from lead L throughbar 11, socket 2, shell G, conductor 9, one of the fuses 4, fuse-contact10, bar 13, and lead L.

The fuse-carrier is of insulating material and the fuses are separatedone from the other by its partitions 1G, and the fuse-con tacts 5 arearranged in recesses 17 in the fusecarrier. The free end of theconductor 9 engages these contacts seriatm when the base and carrier aremoved one in relation to the other. The free end of the conductor 9preferably engages the portions of the fuse-carrier between the recessesin which the fusecontacts are preferably located, and riding over theseportions snaps upon the fuse-contacts and thereby indicates whenconductor 9 is in proper contact with a fuse-contact. Screw 17 l passesthrough the fuse-plug, and in this construction screws into fusecontact10 to clamp the adjacent fuse ends against the disk 1S on the inner endof the f use-carrier. A hood 1 9 supports shell (i, and the shell issecured to it conveniently by the fastenings 2O and 21.

For mechanical convenience shell (3 is formed of two shells, as shown inFigs. 1 and 2, which couple together, and the fuse-carrier at opening 7in said shell is accessible for adjustment, preferably having a stem orhandle which projects through opening 7 and a co1- responding opening inhood 19. The shell is also formed with the opening 8, so as to eX- IOCpose contact lO for connection with the lead L either directly orthrough the electrode 13, as will be plain to all skilled in the artwithout further description. Ordinarily base l is stationary andfusecarrier Z3 rotatable, as shown, and when a fuse in service becomesuseless a fresh fuse is brought inio service by turning the fusescarrier`far enough to bring a fuse between the leads L L.

Preferably, an insulating-shellv 2 is interposed between thefuse-carrier and shell (i to prevent arcing between fuse and shell. Inthe construction above shown f uses lare provided with terminals t, eachof which is in electrical connection with a contact through a screw 5".

In Fig. t3, showing a modification, shell o is electrically connectedwith conductor 9 by a conductor and shell o' couples with the socket, aswill be readily understood. Apart of the hood in this form is a metalliccap.

In Fig. 7, showing another modification, shell U is electricallyconnected with conductor 9 by means of a. conductor llood l() is made intwo parts, as shown, and these parts secured together by screws 2O and2l..

ln Fig. 8 another modification is shown in which conductor i) and shell(j are connected by conductors i225, conductor 9 being supported by aconductor 24.

In Fig. Sl, showing a modification, one set of fuse ends are soldereddirectly to a coninion contact 1S and their other ends are soldered toterminals 25, and these terminals may serve either as the contacts 5 oras the terminals t of the preferred form. lYhen the construction shownin this figure is used, the fuses are bent to bring the contact 1S andterminal 25 into proper position, as will be plain to all skilled in theart without more particular description.

The foregoing modifications are shown to more clearly indicate that myinvention and the different features thereof may be embodied in a greatvariety of different forms without departing from my invention, it beingobvious that my apparatus may be and in many cases must be altered inconstruction in or* der to practically combine a multiple-fuse carrierwith the socket of a cut-out.
